Python - Get localhost IP
There is a nifty module you can use. Its called netifaces. Just do a pip install netifaces into a virtualenv for testing and try the following code:
import netifaces
interfaces = netifaces.interfaces()
for i in interfaces:
if i == 'lo':
continue
iface = netifaces.ifaddresses(i).get(netifaces.AF_INET)
if iface != None:
for j in iface:
print j['addr']
It all depends on your environment. If you only have one interface with one IP address attached to it, you can simply do:
netifaces.ifaddresses('eth0')[netifaces.AF_INET][0]['addr']
If you are behind a NAT and want to know your public IP address, you can use something like:
import urllib2
ret = urllib2.urlopen('https://icanhazip.com/')
print ret.read()
Hope this helps.
I generally use this code:
import os
import socket
if os.name != "nt":
import fcntl
import struct
def get_interface_ip(ifname):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
return socket.inet_ntoa(fcntl.ioctl(s.fileno(), 0x8915, struct.pack('256s',
ifname[:15]))[20:24])
def get_lan_ip():
ip = socket.gethostbyname(socket.gethostname())
if ip.startswith("127.") and os.name != "nt":
interfaces = [
"eth0",
"eth1",
"eth2",
"wlan0",
"wlan1",
"wifi0",
"ath0",
"ath1",
"ppp0",
]
for ifname in interfaces:
try:
ip = get_interface_ip(ifname)
break
except IOError:
pass
return ip
I don't know it's origin, but it works on Linux/Windows.
Edit:
This code is used by smerlin in this stackoverflow question.
